Foreign keys. Tables created using the
NDBstorage engine version 7.3.0 and later provide support for foreign key constraints. (This includes all NDB Cluster 7.3 releases.) For general information about how MySQL 5.6 and NDB Cluster 7.3 handle foreign keys, see Section 18.104.22.168, “FOREIGN KEY Constraints”. For syntax and related information, see Section 13.1.17, “CREATE TABLE Syntax”, and Section 22.214.171.124, “Using FOREIGN KEY Constraints”.
NDB Cluster 7.3 is also supported by MySQL Cluster Manager, which provides an advanced command-line interface that can simplify many complex NDB Cluster management tasks. See MySQL™ Cluster Manager 1.4.3 User Manual, for more information.
